Thank you, that helps, could it be that the gas cap doesn't seal an? Or do you definitely think that I need to replace the DMTL pump?

Any ideas where the vaporized gas smell is coming from?

I have measured the DMTL via Inpa. I ' am getting 4,1 mA of current reference leak, 0 mA of current major leak and 4,3mA of current measurement leak. All values are I'm red zone. Do I need to replace the DMTL pump? The engine was not running at the measurement.
